2 Claims.

This invention relates to sewing machine supports and more particularly to the leg portion of such supports for treadle operated sewing machines.

Heretofore treadle operated sewing machines have comprised a cabinet having a table top on which the head frame is mounted, with side drawers depending from the table top, and legs in the form of metal castings, one for each side of the machine, extending from the floor to the table top, and secured to the under surface of said top adjacent the inner side walls of the cabinet enclosing the drawers.

The main object of this invention is to provide improved means for supporting the cabinet portion of the sewing machine, the treadle, pulley wheel and associated parts.

In the drawings:

Fig. l is a front elevation of a sewing machine embodying my invention.

Fig. 2 is a vertical sectional view, on an en-' larged scale, taken in the plane of the line 2--2 of Fig. 1.

In that embodiment of my invention shown in the drawings, the table top of the sewing machine is indicated as a whole at Ill. Since the table top construction is the subject of my copending application, Serial No. 53,513, filed Dec. 9, 1935, it need not be described in detail herein. The head frame I I is mounted in the top I and supports the sewing head [2.

The cabinet comprises a front wall I3, shield l4, rear wall l5, and drawer enclosing side walls l6.

The legs IT, IT extend from the floor to the lower edges of the inner side walls 16 of the cabinet. Each leg I! comprises a plurality of parallel center bars I8 connected between their upper and lower ends by apertured cross pieces l9, N, a plurality of intermediate parallel bars 20, connected to each other and the center bars l8 by diagonally disposed cross pieces 2|, and a flanged rectangular frame 22 to which the upper ends of the bars l8 and 20, the lower ends of the center bars l8, and some of the diagonal pieces 2| are connected. Preferably the parts constituting the legs I! are metal cast integrally. Bearings 23 for shafts carrying rollers 24 are part of the frame. The two intermediate bars 20 nearest the vertical bars of the frame 22 are provided with drilled holes 25, 26, respectively.

The horizontal portion 21 of the frame 22 is provided with a plurality of upstanding cars 28 and fillets 28 below the ears 28, the ears being apertured to receive screws 29 for securing the leg IT to the side wall 16 of the cabinet. Preferably the ears 28 are not all of the same height so that the screw holes may be in different horizontal planes.

A U-shaped brace 30 has a plurality of centrally disposed fingers 3| by which it is secured to the back wall 15 of the cabinet. Screws 32 secure the ends of the brace to the legs I! in the lowermost of the holes 26. The pulley wheel shaft 33 is fixed in the aperture of the upper cross piece is of one leg 11, and the pulley wheel shield 35 is connected to the leg I! in the uppermost of the pairs of holes 25, 26, by screws 35. The treadle 36 is mounted on a shaft 3! having its ends mounted in the lower cross pieces IQ of the legs H.

The construction and design of the legs I! is such that the operating parts of the machine usually located below the cabinet may be mounted on the legs I! and be properly supported thereon notwithstanding the fact that said legs do not extend upwardly to the table top 10, as is the case in conventional treadle operated sewing machines. The combination of side walls I6, legs I l, and connecting means 2829 provides an efiicient and attractive support for the cabinet and operating mechanism of the machine.

The combination of vertical bars, cross pieces and frame forms legs which are reversible as rights and lefts, and which symmetrically and efliciently support the operating parts mounted on the legs.

Changes may be made in details of construction without departing from the scope of my in- 3 vention and I do not intend to be limited to the exact form shown and described, except as set forth in the appended claims.

I claim:-

1. A sewing machine comprising a cabinet supporting a sewing head and including vertically disposed side walls, metal legs extending from the floor to the lower edges of the side walls of the cabinet, each leg comprising a plurality of vertically disposed bars, an upper and a lower cross bar connected to opposite ends of said vertical bars, the center one of the vertical bars being provided with an upper and a lower reinforced aperture for the reception of the pulley wheel shaft and the treadle shaft, respectively, a plurality of apertured ears extending upwardly from the upper cross bar at points between the vertical bars, reinforcing bosses formed on said upper cross bar beneath each of said ears, and screws connecting each of said ears to the said side walls of the cabinet. 7

V 2,"-A sewing machine comprising a cabinet supporting a sewing head and including vertically disposed side walls, metal legs extending from the floor to the lower edges of the side lower reinforced aperture for the reception of the pulley wheel shaft and the treadle shaft, respectively, a plurality of apertured ears extending upwardly from the upper cross bar at points'beitween the vertical bars, reinforcing bosses formed on said upper cross bar beneath'each ofsaid ears, and screws connecting each of said ears to' the said side walls of the cabinet, the
